Step 3: Tap the Adaptor in with a hammer and a piece of wood/metal until the middlepart of the adaptor is flush with the cylinder tube.
Step 4: Use a 3,5mm drill bit and drill pilot holes 10mm deep into the adaptor.
Step 5: Insert the self-tapping screws, provided with the adaptor. (Ensure that the foot valve is against the Acetal Adaptor).
